Module 1: The Modern Email Authentication Foundation20 Mins

SPF Alignment, DKIM 2048-bit Encryption & DMARC Policy Progression

Since 2024, Google and Yahoo enforce strict email authentication for any domain sending over 5,000 daily messages. Domains lacking SPF, DKIM, and DMARC face instant bouncebacks, rate limiting, and spam box routing.

Topics:SPF 10-Lookup LimitDKIM 2048-bit Key RotationDMARC Alignment (Strict vs Relaxed)p=reject Enforcement

DMARC DNS Configuration Schema

To prevent domain impersonation, deploy DMARC starting at `p=none` for monitoring, then graduate to `p=quarantine`, and finally `p=reject`.

_dmarc.brand.com.zone

_dmarc.brand.com. IN TXT "v=DMARC1; p=reject; sp=reject; pct=100; adkim=r; aspf=r; rua=mailto:dmarc-rua@deliverability.capengage.com; ruf=mailto:dmarc-ruf@deliverability.capengage.com; fo=1"

Key Architectural Takeaways

SPF checks sender IP against the Return-Path domain; DKIM signs message headers with a cryptographic private key.
DMARC requires either SPF or DKIM to be aligned with the visible From: domain header.
A DMARC policy of p=reject instructs mailbox providers to drop unaligned spoofed messages outright.
